To be aligned wit the Libgcrypt code I would prefer to keep the --disable-endian-check configure option. Over there we use:

AC_ARG_ENABLE(endian-check,
              AS_HELP_STRING([--disable-endian-check],
              [disable the endian check and trust the OS provided macros]),
	      endiancheck=$enableval,endiancheck=yes)
if test x"$endiancheck" = xyes ; then
  AC_C_BIGENDIAN
else
  AC_DEFINE(DISABLED_ENDIAN_CHECK,1,[configure did not test for endianness])
fi
